Abstract From cars to airplanes, from household appliances to indoor ornaments, from biomedical devices to factory equipment, epoxy resins have been deeply rooted in modern society. But at the same time, they also bring about a lot of wastes after use due to their insoluble and infusible nature. Vitrimer opens up great opportunities towards to a sustainable society by producing reprocessable epoxies and even thermosets. Epoxy vitrimers are not only the first reported vitrimers, but also the most studied vitrimers. Epoxy vitrimers are reversible covalently crosslinked networks with dynamic covalent bonds, combining excellent mechanic properties of thermosets with reprocessability of thermoplastics. Moreover, the exchangeable network endows vitrimers with excellent reprocessing, self-healing, welding, reshaping and recycling properties. So vitrimers are hopeful to replace traditional thermosets for a wide range of applications in aerospace materials, electronic devices, consumer products of daily life and so on. This review summarizes recent advances in epoxy vitrimer research. The classification and fabrication of epoxy vitrimers and their composites are thoroughly discussed. New properties of epoxy vitrimers brought by the dynamic covalent bonds are also reviewed in-depth. Their potential applications are subsequently explored and summarized.

功能性环氧玻璃体和复合材料

摘要 从汽车到飞机,从家用电器到室内装饰品,从生物医疗器械到工厂设备,环氧树脂已经深深扎根于现代社会。但同时,由于其不溶不溶性,使用后也带来大量废物。Vitrimer 通过生产可再加工的环氧树脂甚至热固性塑料,为实现可持续社会开辟了巨大的机遇。环氧玻璃体不仅是最早报道的玻璃体,也是研究最多的玻璃体。环氧玻璃体是具有动态共价键的可逆共价交联网络,结合了热固性塑料的优异机械性能和热塑性塑料的可再加工性。此外,可交换网络赋予玻璃体优异的再加工、自愈、焊接、重塑和回收特性。因此,玻璃体有望取代传统的热固性材料,广泛应用于航空航天材料、电子设备、日常生活消费品等领域。本综述总结了环氧玻璃体研究的最新进展。对环氧玻璃体及其复合材料的分类和制造进行了深入讨论。还深入回顾了动态共价键带来的环氧玻璃体的新性能。随后探索和总结了它们的潜在应用。还深入回顾了动态共价键带来的环氧玻璃体的新性能。随后探索和总结了它们的潜在应用。还深入回顾了动态共价键带来的环氧玻璃体的新性能。随后探索和总结了它们的潜在应用。
